• Using ssh for remote command

  - by user1663479

  I need to use ssh to execute a remote command such as: ssh -l jsilva xman /vol/2011/linux_x64/exe/mx201111.exe When I execute ssh I receive error message: /cmg/2011.11/linux_x64/exe/mx201111.exe: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory This application uses the variable LD_LIBRARY_PATH. I inserted this variable into /etc/profiles in localhost and remote host. The filesystem /cmg is mounted by autofs for both hosts (local and remote). Anybody have idea how to resolve this problem? Thanks!

• How to add external library properly in Eclipse?

  - by Peter

  So today I downloaded Apache Commons Lang library (binary, zip format). I extracted it to C:\eclipse\commons-lang-2.5 folder. There are a commons-lang-2.5.jar, a commons-lang-2.5-javadoc.jar, and a commons-lang-2.5-sources.jar inside, and a folder for HTML Javadoc. I started Eclipse, added commons-lang-2.5.jar, and set its source and Javadoc respectively as the screenshot below. My question is, is there a convenient or standard way to add external libraries? Or am I actually doing the right thing?

• What is a good Java web crawler library?

  - by DrDee

  Hi, I am about to develop a crawler in Java but don't feel like reinventing the wheel. A quick Google search gives a whole bunch of Java libraries to build a web crawler. Besides that Nutch is of course a very robust package but seems a bit too advanced for my needs. I only need to crawl a handful websites a week containing a couple of 1000 pages each. Which open source Java library would you recommend considering: speed multithreading (or even distributed) extending it with new functionality active maintained and documentation?

• ASP.NET plug-in architecture, settings problem

  - by Xaqron

  I want to divide business layer (BLL) of an asp.net application into multiple components. Each component is a .NET class library which is compiled as a standalone DLL. These components should have their own configuration files. For example "MyNameSpace.Users.dll" contains classes about users of the website and there's a password policy to check if password length is at least x characters. When webmaster edits the config file of this DLL and set x to y then component (DLL) should use new value (y) in the future and enforce passwords to be at least y characters. I want each component as a single project and compile them separaely (and not to put all projects in a solution in Visual Studio), and put the DLLs of these libraries into the "Bin" folder of my ASP.NET application. Is it possible ? Where should I put these config files ?

• Standard way of distributing source code?

  - by penyuan

  I am relatively new to programming, and have built a few working C++ commandline programs with Xcode in Mac OS X (no dependencies on Mac-only libraries or APIs). My question is: What is the standard way of packaging and distributing the source code (and possibly compiled binaries)? i.e. Almost all Linux programs seemed to be distributed that a user simply needs to run ./configure && make && make install from the source directory. Thank you.

• "No context-sensitive help installed" , "user32.dll" and "uxtheme.dll" AV errors on Delphi with no reason

  - by Javid

  This is very strange guys. I wrote a simple application. When I make my commands executed fast by moving mouse (event is on mouse move), I experience the following errors if I run my application without debugger (if I do, application just hangs and nothing happens): 1- "No context-sensitive help installed" however i haven't used help in my app. 2- Access violation errors from "uxtheme.dll" and "user32.dll" libraries! well, i think these errors happen when Windows Messages are sent quickly one after another. I came across these errors a while ago in a huge application. In both application I used SendMessage command, but what am i doing wrong? I'm now using Delphi 2010 Has anyone ever experienced this?!

• How cross-platform .Net framework really is?

  - by Ivan

  What is normally to be done to run a WinForms application on a Mac or Linux machine? a. Just copy and run (assuming they have a Framework installed). b. Rebuild. c. Cosmetic source code modifications. d. Heavy source code modifications and forms redesign. Assuming that the application is developed as 100% managed C# 3 code by means Visual C# Express or Visual Studio 2008 targeting .Net Framework 3.5, developed without using any 3-rd party components/libraries, without encapsulating nonmanaged code or any low-level hacks - only standard Microsoft-documented .Net Framework C# API used). Or the same conditions but C# 4 language, .Net Framework 4 and Visual Studio 2010.

• Simple File-based Record Storage with Fast Text Searching for Compact Framework and Silverlight

  - by Eric Farr

  I have a single table with lots of records ( 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL). I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually. The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format. I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

• Is there a Java Package for testing RESTful APIs?

  - by Zachary Spencer

  I'm getting ready to dive into testing of a RESTful service. The majority of our systems are built in Java and Eclipse, so I'm hoping to stay there. I've already found rest-client (http://code.google.com/p/rest-client/) for doing manual and exploratory testing, but is there a stack of java classes that may make my life easier? I'm using testNG for the test platform, but would love helper libraries that can save me time. I've found http4e (http://www.ywebb.com/) but I'd really like something FOSS.

• Error Using PDCurses: Cannot Open File Libc.C

  - by cam

  I'm getting the error: 1>LINK : fatal error LNK1104: cannot open file 'LIBC.lib' Here's my source code: #include <curses.h> int main() { initscr(); /* Start curses mode */ printw("Hello World !!!"); /* Print Hello World */ refresh(); /* Print it on to the real screen */ getch(); /* Wait for user input */ endwin(); /* End curses mode */ return 0; } I've configured the PDcurses library properly (added to Additional Include libraries, added folder to Additional Library Directories). I've looked around for a bit, and I've tried adding Libc.C to the 'Ignore Library' list, which in turn causes about 150 errors. Not sure what to do from here.

• "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1

  - by param

  I am getting some "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1. Is this due to a wrong combination of libraries that I am using? App Type: Windows Phone 7.1 Using: 1) sql-net Version 1.0.5, Source Nuget thru Visual Studio 2) C# Sqlite for WP7 (wp7sqlite) ( Community.CSharpSqlite.WP7) Version 0.1.1, Source Nuget thru Visual Studio. The exact error I receive is below **Error 5 The best overloaded method match for Community.CsharpSqlite.Sqlite3.sqlite3_open(string, ref Community.CsharpSqlite.Sqlite3.sqlite3)' has some invalid arguments C:\Dev\Learning\SQLite.cs Line:2492 Column: 29 ** The next error then hints that it is related to the parameter being passed as "out" type instead of "ref" type. Error 6 Argument 2 must be passed with the 'ref' keyword C:\Dev\Learning\SQLite.cs Line: 2492 Column: 64 I can make the compile errors go away by replacing the "out" keyword with the "ref" keyword, but that is likely to lead to other issues. Given that I do not see much complain about this issue - I may be doing something wrong but not able to detect easily. Thanks, Parmeshwar

• How to write a shell in Python

  - by panzi

  I've written a small console application that can perform certain tasks. The user interface is similar to things like version control systems or yum etc. So basically you can think of it as a domain specific language. Now I'd like to write a (bash like) shell that can execute and auto-complete this language and has a command history (so I do not have to load and save the quite large xml files on each command). In a nutshell I want something like ipython but not for executing python code but my own DSL. Are there any libraries that help me doing this? I see that there is a readline and rlcompleter module in python but its documentation seems to indicate that this is only for use with the python shell itself, or did I miss something there?

• Alternative to BerkeleyDB?

  - by John

  I'm looking for a dbm-like library that I can use in place of Berkeley DB, which I'm currently using. My main reason for switching is the licensing fees for BDB are pretty high (free for open source apps, but my employer does not want to open source this particular app for various reasons). I've looked briefly at qdbm but it doesn't look like it will fill my needs -- lots of keys (several million) and large data items ( 1-5 megabytes). Before I continue my search I figured I'd ask because it seems there are tons of dbm-like libraries out there.

• Synchronizing Java Visualizer Audio and Visual

  - by Matt

  I've run into a problem creating a visualizer for .mp3 files in Java. My goal is to create a visualization that runs in time with the .mp3 file being played. I can currently visualize an .mp3 OR play it, but not both at the same time. I am using libraries which may make this trickier than necessary. I currently: Read in the .mp3 as a FileInputStream. a) Convert the FileInputStream into a Bitstream and run the Visualizer OR b) Pass the FileInputStream to a library Play method where it converts it into a Bitstream, decodes it, and plays it. I am using the JLayer library to play and decode the .mp3. My question is: how do I synchronize the two actions so that I can run both at the same time AND they line up (so my visualizations correspond to the changing frequencies). This implies that they finish at the same time as well.

• Anyone got Twitter xAuth working with the Compact Framework yet?

  - by peSHIr

  This question is related to a number of other questions on oAuth on the Compact Framework (one, two) but seems slightly more specific to me, as it specifically involves getting Twitters xAuth API call (meant for non web applications to be able to do oAuth) working on the Compact Framework. Are SSL HTTP connections and the encryption methods needed for xAuth needed part of Compact Framework 3.5? Did anyone get the Twitter xAuth working on Windows Mobile already? If so, what libraries did you use for this? Any tips are welcome.

• Bulding an multi-platform SWT application using Ant

  - by Mridang Agarwalla

  I'm writing an SWT application which can be used on Windows (32/64 bit) and Mac OSX (32/64 bit). Apart from the JRE I rely on the SWT library found here. I can find four versions of the SWT library depending upon my target platforms (as mentioned above). When building my application, how can I compile using the correct SWT Jar? If possible, I'd like to try and avoid hard-coding the Jar version, platform and architecture. The SWT Jars are named like this: swt-win32-x86_64.jar swt-win32-x86_32.jar swt-macosx-x86_32.jar swt-macosx-x86_64.jar (My project will be an open source project. I'd like people to be able to download the source and build it and therefore I've thought of including all the four versions of the SWT Jars in the source distribution. I hope this is the correct approach of publishing code relying on third-part libraries.) Thanks everyone.

• Finding matches between multiple JavaScript Arrays

  - by Chris Barr

  I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

• Silent Printing of PDF From Within Java

  - by Paul Reiners

  We are looking into silent printing of PDF documents from within Java. The printing will be invoked from the desktop and not through a browser so we cannot use JavaScript. PDF Renderer is an operational solution but their rendering quality is not acceptable. iText does not seem to be pluggable with the Java print service. There are some commercial Java libraries, jPDFPrint by Qoppa, JPedal, and ICEpdf which we have not tried out yet. Does anybody have any experience with PDF silent printing from Java?

• java tool for debugging

  - by user269723

  Hi experts, Currently we are studying the java based tool which is primararily Reporting tool.It was developed in 2000/2001 period and uses many open source libraries like Apache Avalon/Mx4J.Adaptor/edu.Oswego(java concurrent package) etc. Tool uses jdk 1.3.1 and goal is to upgrade to jdk 1.5.We have also been asked to remove these 'outdated' packages and replace by standard java packages if possible. Unfortunately we have the code available for study but lacks any documentation and really difficult to track the flow(Total number of classes written might be more than 1000) during debugging. Whats the best way to understand this kind of tool? any Graphical tool to see the relationship between the classes? Thanks SR

• Upload files with java

  - by Marius

  I'd like to upload a few files to a http server. Basically what i need is some sort of a post request to the server with a few parameters and the files. I've seen examples of just uploading files, but didn't find how to also pass additional parameters. So the question would be what's the simplest and free solution of doing this? Does anyone have any file upload examples that i could study? I've been googling for a few hours, but (maybe it's just one of those days) couldn't find exactly what i needed. The best solution would be something that doesn't involve any third party classes or libraries. Thank you

• Should I be so enthusiastic about Groovy?

  - by rukoche

  I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

• How can I create an .xls file with a readwrite password from Delphi

  - by dummzeuch

  I know that it is possible to create .xls files from Delphi using ADO, OLE automation with Excel and even using several commercial libraries. My requirement now is not just creating a new .xls file and adding data to it but in addition protecting it with a password against editing. I guess this would be possible using OLE automation but that would require an Excel installation on the computer and also add all the potential hassle of OLE automation which I would like to avoid. Does any of the other solutions provide the option of password protecting the file? (Yes, I know this is far from secure, but the customer requests it. Just in case it matters: I am using Delphi 2007.)

• Generate an image / thumbnail of a webpage using X/Gui-less linux

  - by dassouki

  There are a lot of solutions out there on generating a thumbnail or an image preview of a webpage. Some of these are websites like websnapshots, windows libraries such as PHP's imagegrabscreen (only works on windows), and KDE's wkhtml. Many more do exist. However, I'm looking for a GUI-less solution. Something I can create an API around and link it to php or python. I'm comfortable with python, php, C, and shell. This is a personal project, so I'm not interested in commercial applications as I'm aware of their existence. Any ideas?

• How to access USB ports in java

  - by Petezah

  Hi I'm trying to write a java application that accesses the usb ports to some read and writes to a device connected through usb. The problem I face is that I don't know what exactly to use in java to do such a thing. I searched online a found something called jusb but all the post seem fairly old. Currently I'm using the RXTX libraries but I sometimes run into some sync error. When I use C# to do the equivalent it requires far less code and I don't face any of the same sync error. My question is there anything built into the latest version of the JRE I can use to access the usb ports that is just as easy as the equivalent C# code? Sorry if the question isn't too clear, I'm fairly noob with coding usb IO.

• DocuSign Connect xsd [on hold]

  - by Brian

  I'm trying to parse xml inbound to our system from the DocuSign Connect service (which publishes status updates to a given web service). I typiclly use jaxb to process xml but as far as I know I need xsd's in order to generate the jaxb. I don't have (or can't find) xsd's from DocuSign in order to do this. I could use other java classes/libraries to parse the xml but without xsd's I'd have to guess at types, restrictions and formats. Is there a way to generate jaxb without having xsd's?
